Hadith.297 - Imam Hasan ibn Ali (as) came out of the bathhouse, and a man met him and said: "May your (backside) bathing be good." Imam (as) said: "O’ fool, what business do you have mentioning the ‘backside’ here ?" (The man) replied: "May your bath be pleasant" Imam (as) said: "And if my bath is pleasant, what benefit is that to me?" (The man) replied: "May your warm water be pleasant." Imam (as) said: "Woe to you! Do you not know that 'Hamim' (hot water) is sweat?" (The man) asked Him: “So what should I say?” Imam (as) said: "Say: 'May what is purified from you be pleasant, and may what is pleasant from you be purified.'".
